| 摘 要： | 在简述电压暂降的基本概念、特征量和起因的基础上,介绍了采用有效值算法获取电压暂降特征量的方法,提供了完整的软件处理流程。通过Matlab仿真,验证了全周期有效值算法和半周期有效值算法的有效性,得出了电压暂降起始时刻和终止时刻的延时误差变化曲线。在对起止时刻精度有较高要求的场合,可以利用该曲线进行误差修正,进而得到更为准确的电压暂降持续时间。 |

| Abstract: | According to the basic concepts,characteristics and causes of voltage sags,a root-mean-square（RMS） algorithm method to obtain the characteristics of voltage sags was introduced and a complete software process flow was provided.Through the Matlab simulation,the full-cycle RMS algorithm and the half-cycle RMS al-gorithm were proved and the delay error curve of the start time and end time of voltage sags was obtained.On the occasion for higher precision demand of start-stop time measurement,a more accurate voltage sags duration could be obtained after the error correction by the curve. |
| Keywords: | voltage sags detection method root-mean-square（RMS） algorithm |
